then there's the question of whether any and all Pd patches are
'derived works' (derived from Pd) or '[a combination of] two modules into

Most externals are GPL'ed (and therefore Pd-extended too), so
there you have to watch.does this mean it makes a difference if I use a library from within
pd-extended or install it myself?Technically, yes, but in reality, not really. If someone tried to
enforce the GPL on you, then you'd just have to make your own custom
build using the BSD licensed code.from my understanding GPL is more restrictive than the Pd license
(BSD). because it forces me to publish whatever I create under GPL
again. does working with a library that is gpl force me to open source my
pd patch? is a pd patch a derived software at all? and if yes,
which are the libraries that can be used without problems? marius.That's an interesting question. I think that if you write a patch
that uses a Pd library that is covered by the GPL, technically, your
patch is covered by the GPL. If those libs used the LGPL then you
would not. It's a bit of a gray area, but I release all my code
under the GPL, so I haven't really worried about it.
not that i am an expert in this field myself, but i have the strong feeling (and iirc, i was told so), that this is not true. a song made in cubase is not affected by the license of cubase. a patch made in pd is not affected by the license of pd and is basically only a text-file with no relation to the source of pd nor to any external nor is it statically linked nor is it a derivate of the pd source code (one could perfectly write a pd-patch without touching pd at all nor reading the source of pd). as long as the patch is distributed without pd's or any external's source code, you are free to distribute it under whatsoever license you want. and i am pretty sure, that the same rules also apply on one level up: the songs you create with my patches are not affected by the license i gave to my patches. the songs you made with my patches derive from a legal point of view from your creativity (not mine) and therefor fall under your copyright (and are not affected by the license of my patches).
ask a lawyer to check in detail, if this is true. however, if licenses could cross 'levels of abstractions' in the sense of pd patches being affected by the license of pd, actually nothing could published anymore without violating licenses (or everything would need to be distributed under the same or compatible license).
